| Description: |
AbstractA patch antenna was realized utilizing a Li₂MoO₄ disk fabricated by a room‐temperature densification method, where the densification takes place during pressing. Therefore, the size of the ceramic can easily be managed by controlling the mold dimensions, making this method advantageous for patch antenna design. The antenna showed reasonably good performance. A relative humidity of 80% lowered the resonant frequency and reduced the efficiency of the antenna. Use of a conformal coating reduced the changes and speeded up their reversibility. The results show that the room‐temperature densified Li₂MoO₄ ceramics are feasible for use under high humidity with a silicone coating. see all
